Portsmouth to Gatwick Airport: Train, Coach, Bus, Car & Complete Travel Guide

Portsmouth to Gatwick at a Glance

Four ways to make the journey, one row each. Third-party fares and times fluctuate — verify at source before you travel.

* Third-party fares indicative — check the operator for live prices.

Journey overview. People travel this corridor for flights, for the naval and ferry connections Portsmouth itself offers, and for the South Coast's wider commuter links into the South East. Journey time by road or direct train both sit close to an hour and a quarter to an hour and a half — the coach takes noticeably longer.

Understanding the Distance Between Portsmouth and Gatwick

This is worth being upfront about: published sources disagree on this more than on almost any other route we've researched.

What is the road distance? Several sources converge on around 75.4 miles, taking around 1 hour 16 to 19 minutes via the A3 and M25. One aggregator source gives a noticeably shorter figure, around 60 miles and 1 hour 13 minutes. We're treating 75.4 miles as our working figure, since it's corroborated by the named A3-M25-M23 route — a well-documented, specific road path. The shorter figure isn't tied to a comparably specific route description in what we found.

Why different sites show different distances. Driving distance (the actual road path) and straight-line distance (a direct point-to-point measurement) can differ substantially on a route like this, where the A3 curves through Guildford and Petersfield rather than running straight. Some tools also calculate a fastest-route estimate that differs from a standard route depending on which motorway junctions and A-roads they favour. Some aggregator tools blend driving and rail distance data in ways that aren't always clearly labelled, which can produce a shorter 'distance' figure that doesn't actually reflect the road journey.

Which distance should travellers use? For planning a road journey specifically, 75.4 miles and a journey time of 1 hour 16 to 19 minutes is the figure corroborated by a named, specific route. Use the shorter published figures with some caution unless the source specifies exactly which route and measurement method they used. We weren't able to find a clean, separately-measured outbound versus return distance for the driving route specifically — the sources we found publish a single figure rather than two directional readings.

Portsmouth to Gatwick by Train — a Genuine Direct Service

Is there a direct train? Yes — and this is one of the better direct rail connections into Gatwick from outside London. Southern operates a direct service running throughout the day.

Operators and route. Southern operates the direct through-service. South Western Railway also serves both Portsmouth stations, though some of its journeys to Gatwick involve a change rather than running direct — check the specific service before booking if a direct train matters to you. The direct Southern service runs without a change, via the coastal and Sussex mainline route towards Brighton before turning north for Gatwick. A small number of journeys shown by aggregators involve changing where a South Western Railway and Southern combination is used instead — always check whether your specific chosen departure is direct.

Timetable, time and price. On the Portsmouth & Southsea to Gatwick route, the first direct train departs at 04:52, with the last around 22:57. On the return leg, Southern's published timetable shows the last train from Gatwick to Portsmouth Harbour departing at 21:09, with around 27 direct services running that day. The fastest direct journeys take around 1 hour 27 to 32 minutes; the average across the day, including some slower stopping services, is closer to 1 hour 46 minutes. Fares start from around £9 one-way, though rail fares vary by ticket type (Advance, Off-Peak, Anytime) and how far ahead you book.

Luggage and pros/cons. Southern's direct service has standard luggage racks and overhead storage; seat reservations aren't available on Southern services, so arrive a little early at busier times to secure space for yourself and your bags. Bicycles are permitted, with some peak-time restrictions. The direct service, frequent departures and journey time close to driving make this one of the stronger rail options into Gatwick from outside London. The trade-off against a taxi is the usual one: no seat reservation at busy times, and getting yourself and your luggage to the station in the first place.

Portsmouth Harbour vs Portsmouth & Southsea — Which Station for Gatwick?

Functionally, either. Every direct train that calls at Portsmouth Harbour also calls at Portsmouth & Southsea a couple of minutes later, since Southsea sits on the same line towards Gatwick — neither station has a connection the other lacks.

• Journey time: the difference is small — a few minutes, reflecting Southsea's position slightly further along the route than the Harbour terminus. Not enough to meaningfully change your planning either way.
• Ticket price: we didn't find a consistent, meaningful fare difference between the two stations; any small difference is more likely down to which specific train and ticket type you book than which station you start from.
• Accessibility: both stations are served by the same operators (Southern and South Western Railway) and offer step-free access and assistance — check each operator's own accessibility pages for facilities on your travel day.
• Parking: both stations offer nearby parking, though as a terminus right on the harbour, Portsmouth Harbour also connects directly to the Isle of Wight and Gosport ferries, which may matter if you're combining journeys.

Which should visitors choose? Whichever is closer to where you're actually staying or arriving from. If you're coming off a ferry, Portsmouth Harbour is the natural choice since it's the terminus right by the ferry terminal. If you're already in the Southsea area or the city centre, Portsmouth & Southsea is usually the more convenient stop, without costing you anything in journey time.

Portsmouth to Gatwick by National Express Coach

Does National Express operate this route? Yes, on route 206, currently priced from around £7 one-way on aggregator sites — and it runs direct.

Timetable and duration. The 206 service runs up to 6 times a day from Portsmouth, departing from The Hard Interchange. National Express's own published fastest journey is 1 hour 35 minutes, though aggregator data shows some journeys taking considerably longer — up to around 2 hours 37 minutes on average for all direct departures, and longer still for journeys involving a change.

Price and boarding. Aggregator fares start from around £7 one-way, though prices are demand-based and change daily. National Express also offers a 'Change and Go' option, letting you board any coach within 12 hours of your original booking for a £5 fee if your plans shift. Coaches depart from The Hard Interchange in Portsmouth city centre. At Gatwick, National Express uses the lower level outside International Arrivals at North Terminal, with South Terminal services using the lower forecourt stops 1 to 5.

Luggage and the trade-off. You can bring one large suitcase (or two medium cases) plus one soft hand luggage item per passenger. National Express's fastest published journey (1 hour 35 minutes) is genuinely competitive with the train, and coach fares tend to undercut the train on price. The trade-off is that the fastest journey time isn't guaranteed on every departure — check the specific journey time for your chosen departure rather than assuming the fastest figure applies.

Coach vs train. The train is generally faster on its best services (1 hour 27 minutes against the coach's 1 hour 35 minutes), and more frequent across the day. The coach is generally cheaper. Neither requires a change on their direct services, so the choice mostly comes down to price against the small time saving. 'Bus' and 'coach' point to the same National Express service on this corridor — we haven't found a distinct local bus service that also reaches Gatwick.

Portsmouth to Gatwick by Car

The route, the running costs, and how driving compares.

Route and time. Around 75.4 miles by our working figure. The recommended route runs via the A3 (picking up the M275 and A27 out of Portsmouth first), then onto the M25, then the M23 south to Gatwick at Junction 9 — around 1 hour 16 to 19 minutes under normal traffic, one of the faster corridors into Gatwick we've researched. The A3 itself is a mix of motorway-standard dual carriageway and A3(M) sections; the M25-M23 stretch at the end is the part most exposed to traffic, as on most routes into Gatwick from this direction.

Fuel. For the roughly 75-mile one-way trip, expect to use around 1.9 UK gallons (8.5 litres) of petrol at a typical 40mpg, or around 1.5 UK gallons (6.8 litres) of diesel at a typical 50mpg.

Drop-off and parking. Gatwick charges £10.00 for the first 10 minutes to drop off at the terminal forecourt, in force since January 2026, with a Blue Badge exemption under the airport's own policy — that works out at 8.2 per cent on top of our own £121.52 saloon taxi fare. Short Stay, Long Stay and premium or valet parking are all available at both terminals; Short Stay rates start from around £7.00 for up to 30 minutes, with Long Stay offering the first 2 hours free before daily charges apply. As with any route feeding onto the M25, weekday morning and evening peaks are when journey time is most likely to run over our 1 hour 16 to 19 minute estimate.

Does Gatwick Express Go to Portsmouth?

No — and this is an easy, common mix-up worth clearing up.

What Gatwick Express is. Gatwick Express is a non-stop rail brand running only between London Victoria and Gatwick Airport, taking around 30 minutes, with services extending to Haywards Heath and Brighton — not to Portsmouth. It's operated by Govia Thameslink Railway, the same parent company that runs Southern.

Why it doesn't serve Portsmouth. Gatwick Express was built specifically as a fast, non-stop London-to-airport link, not a wider regional network — it simply doesn't run in Portsmouth's direction at all. The direct Portsmouth-Gatwick service is run by Southern, a sister brand under the same parent company, but a genuinely different train, route and timetable. Because Gatwick Express and Southern are both part of the same parent company and both serve Gatwick, it's an easy mix-up to assume Gatwick Express covers every route into the airport. It doesn't — Southern's direct Portsmouth service, covered above, is the one that actually applies to this journey, not a routing via London Victoria, which would add an unnecessary change.

Portsmouth to Gatwick Journey Comparison

Every option side by side.

Reliability, comfort and environment. We don't have route-specific, verified punctuality data for this corridor and aren't going to estimate one — check each operator's own live service updates for current performance. Comfort is subjective: a taxi offers a private vehicle; the train and coach both offer Wi-Fi and power, with the train generally regarded as the smoother ride given fewer road-traffic variables.

Planning Your Journey, and Arriving at Gatwick

Check which Gatwick terminal you need before you travel — North and South are connected by a free shuttle, and both are served by direct trains and coaches. Given the direct train and coach both run close to 1.5 hours at their fastest, build in extra time beyond the journey itself for check-in and security, particularly at peak travel periods.

• North Terminal: National Express coaches serve North Terminal directly at the lower level outside International Arrivals.
• South Terminal: the direct Southern train arrives into Gatwick's main station, integrated into South Terminal; National Express coaches also serve South Terminal's lower forecourt stops. Gatwick's station sits inside South Terminal itself — a free inter-terminal shuttle connects to North Terminal in a few minutes if you need it.
• Coach & bus stops: check your specific ticket for the exact stop and stand, since these vary by operator and by which terminal your service is booked to.

Travel tips: outside weekday peak hours if driving, and on a confirmed direct service if taking the train — check your chosen departure doesn't involve an unexpected change. Book train and coach tickets in advance where you can. School holidays and weekend mornings can mean busier trains and coaches, and heavier M25-M23 traffic for drivers; some services and timetables, particularly on Sundays, can differ from the weekday pattern. Rail engineering works can affect this corridor, as with any UK route — check live service updates close to your travel date.

Choosing the Best Way to Travel from Portsmouth to Gatwick

Portsmouth is one of the better-connected corridors into Gatwick we've researched — a genuinely direct train, a genuinely direct coach, and a road route that beats both on raw journey time. If budget matters most, National Express edges out the train on price alone. If you want the best combination of speed and value, the direct train is hard to beat on this specific route. And if door-to-door convenience, luggage flexibility or travelling with young children matters more than the fare, a taxi remains the most straightforward choice, even though it costs considerably more than either public transport option.

• ✔ Fixed fare from £121.52 saloon, indicative and confirmed at booking against your exact Portsmouth address
• ✔ Direct alternatives exist and cost less: Southern train from ~£9, National Express 206 from ~£7
• ✔ Meet & greet, flight tracking, 45–60 min free waiting, no surge, 24/7
